INSPECTION DATE Sanuary 15, 1998
INSPECTOR'S INITIALS TAS
1. A site inspection was made of the Brannan Sand & Gravel Company Pit No. 29 located near
132nd & Nome Streets in Brighton. Present during the inspection was Mr. Fred Marvel of
Brannan Sand & Gravel Company.
2. Pit No. 29 is permitted for 145.5 acres of affected land with a financial warranty of
$89,435 in the form of a corporate surety. The designated post-mining land use is wildlife
habitat, lakes and backfilled areas with potential for residential or commerical development.
Completion of the reclamation plan will result in the creation of 2 lakes, 1 of 62 acres and
another of 38 acres. Backfilling will occur along both lakes to create potential residential
and industrial sites. The shores of the lakes will be sloped at a grade of 3:1 or less,
except for the adjacent backfilled areas which will be sloped at a grade of 5:1 to a depth
of 6 feet below the water line. Shorelines will be left somewhat irregular and some shallows
may be constructed for wildlife uses.
3. The operator is nearly complete with mining in the Phase 2 area and is beginning to strip
topsoil in the Phase 4 area. There are approximateley 70 acres currently disturbed. All
disturbance was found to be within the permit boundary. Although mining has been completed
in the Phase 1 area this inspector estimates that approximately 193,600 cubic yards of
overburden fill are needed to achieve the desired post-mining contours in the area to be
reclaimed to industrial/commercial use. The majority of the Phase 1 and 2 areas has been
partially reclaimed to a 38 acre lake. Grading and topsoiling is still needed for the north
and east shorelines of the lake. The main processing area for the minining operation is
located in the Phase 3 area and encompasses approximately 6.5 acres. Nearby are several
flatbed trailer loads worth of non-roadable mining equipment. Near the entrance to the mine
site, in the northeast corner of the Phase 1 area is an old non-roadable dragline and a large
truck scale with concrete foundation.
4. There are no wash ponds present or discharges from the mining operation. The operator
uses a "wet mining" method with dragline and allows the excavated sand & gravel to dry before
loading and hauling to the processing plant. The operator has obtained a temporary
substitute supply plan from the Office of the State Engineer to mitigate for evaporative
loss.
5. An entrance sign was posted and the permit boundary was marked as required by Rule
3.1.12.
6. There are weeds present, although none are considered to be noxious.
7. The Division has calculated a total reclamation cost of $413,400 in order to complete the
reclamation plan, based on the current and planned disturbance in all phases of the
operation. Attached is a copy of the reclamation cost and supporting calculations. This
cost is significantly higher than the existing financial warranty of $89,435. The Division
considers this matter to be problem that will require corrective measures by the operator
within a period of 60 days. Several corrective measures are available to the operator: Otion
1, submit a replacement warranty of $413,400 or a supplemental warranty of 323,965; Option
2, submit an application for an amendment to the permit which may result in more cost
effective mining ~ reclamation and a lower reclamation cost; Option 3, perform reclamation
to reduce the current reclamation liability; or Option 4, some combination of the above.
